I need a replacement for the 3 sealed lead acid batteries in the Black & Decker "Simple Start". It sat too long & sulphated. The batteries are "SEL C83-6"

..

the sulphuric acid reacts with the lead in the plates with the result that the acid breaks down and tends to go water and the lead becomes lead sulphate
when a battery is dead flat, the plates are all lead sulphate and the density of the acid is approaching that of water
that can be tested with a hydrometer
When a charge is applied to the battery terminals , the process is reversed and the lead sulphate returns as lead and the water ( low ph acid) returns to sulphuric acid

http://www.atbatt.com carries a large array of sealed lead acid batteries. I did a search for 12V 2.8ah and here is one of the results:

This is a high charging on the battery, as it is overcharged . this can be failure of the alternator rectifier or the regulator.
so use a voltmeter and confirm the voltage range to rectify the fault.
A high charging of this nature can damage the battery in the long run.

I discuss the solution to your problem in my review. I am using a replacement AGM Lead Acid battery that increased my mowing distance and does not take more power to charge because the battery has an lower internal resistance. The battery is a Power Sonic, PSH-12180FR, 21Amp Hour unit. You will need to order two of them.

We should all do our part to save the enviroment and encourage the growth of the solar and wind power industries.

Cordless electric lawn mowers go a long ways towards these goals. I recently purchased the Black & Decker Cordless Electric Lawnmower the CMM1200.

In the review I describe how to upgrade the mower to mow over 9,000 SQFT!

I hope my review will help you make a decision about our future.
